Problems With Bose S1 Pro Bluetooth Speaker System

Here is a list of those issues:

• Power and Electrical Issues
• Sound Quality Issues
• Wireless and Connection Problems
• Physical Damage and Durability Concerns
• Setup, Configuration, and Control Difficulties

Let’s talk about them in detail.

Power and Electrical Issues

One of the most frustrating problems with the Bose S1 Pro is when it won’t turn on or simply stops outputting sound unexpectedly. There are a few root causes that could lead to these power and electrical issues:

• Faulty power cable

Like any electronic device, the S1 Pro relies on a good connection to electricity to operate properly.

If the power cable is damaged or loose where it connects to the speaker or wall outlet, it can disrupt power delivery and cause startup or operation problems.

Inspect the power cable thoroughly and try swapping it out with a different cable to see if that fixes any power issues.

• Blown internal fuse

The S1 Pro has an internal fuse that protects its amplifier circuitry from power surges.

But this fuse can occasionally blow from a significant spike in electricity.

You’ll need to have the fuse replaced by an authorized Bose repair center to get your speaker working again if this is the cause. Avoid plugging into outlets with questionable wiring that could cause voltage fluctuations.

• Overheating issues

Though rare, some S1 Pro units have overheated from prolonged use at high volumes, causing temporary or permanent electronic failure. Make sure air can freely circulate around the unit while operating.

Also give the system a break and time to cool down if you’ve been running it hard for an extended period.

• Power port problems

The power input jack on some S1 Pros can become loose or damaged over time. This affects the connection with the power cable and results in intermittent power.

If wiggling the cable seems to make sound cut out, you may need to replace the power input port or use an alternate connection method.

• Battery failure

The built-in rechargeable battery on the S1 Pro provides up to 11 hours of cordless runtime. But eventually this battery will wear down and no longer hold sufficient charge. Replacement batteries can be sourced online as long as you’re comfortable performing the swap yourself.

Sound Quality Issues

When a speaker stops sounding as good as it should, it renders the device essentially useless. Here are some sound quality issues that S1 Pro owners have reported:

• No audio output – As covered in the power section, no sound can point to electrical problems, but also check that your source audio device is actually sending signal to the S1 Pro. Try different cables and source devices to isolate the issue.
• Intermittent or distorted sound – Similar to power problems, loose wiring and faulty components can cause the audio signal to become interrupted or mangled on its way to the speakers. If the issue persists after checking cables, a service repair may be needed.
• Muddy or unclear audio – While the S1 Pro produces nicely balanced sound for most users, some have described the tone as being too boomy or muddy. Make sure any onboard EQ settings aren’t dialing up the bass too high. Also try repositioning the unit or adjusting its angle/direction to even out the response.
• Poor bass performance – Low-end power is one of the S1 Pro’s strong suits, so weak bass response is likely due to placement choices and acoustic interactions. Move the speaker away from corners and walls and try tilting it back slightly to improve bass output.
• Excessive distortion at high volumes – The S1 Pro can’t handle extremely high volume levels without some eventual distortion or breakup. Keep the volume at reasonable levels to avoid pushing the unit beyond its amplifier capabilities. Turn down bass EQ settings as well.
• Not enough volume/lacks “punch” – While capable of impressive volume for its size, the S1 Pro does have limits. Make sure your expectations are realistic for a single compact PA speaker. Adding a powered subwoofer can help increase low-end volume and impact.

Wireless and Connection Problems

One of the S1 Pro’s best features is its robust wireless functionality. But this reliance on Bluetooth and Wi-Fi also introduces some potential for connectivity problems.

• Pairing issues – Make sure Bluetooth is enabled on your source device and that it is within 30 feet of the S1 Pro for pairing. Re-initiate the pairing process if the wireless connection is spotty. Also check for interference from other wireless devices in use nearby.
• Intermittent signal drops – Stay within the effective wireless range and have a clear line of sight between your device and the speaker. Reduce signal congestion from other wireless networks/devices as well. Switch to a wired connection if possible.
• App connection problems – The Bose Connect app allows wireless control and access to additional features. But some users report trouble staying connected to the app or getting it to recognize the S1 Pro. Make sure the speaker firmware is up to date and reinstall the latest app version.
• Wi-Fi network issues – To use Spotify Connect, AirPlay 2, and other streaming features, the S1 Pro must be connected to your Wi-Fi network. Verify your Wi-Fi password is correct during setup. Try moving the speaker closer to the access point temporarily to establish a solid connection.
• Not connecting automatically – The Auto-On feature is supposed to detect an incoming audio signal and power on the S1 Pro automatically. But it can be hit or miss in terms of reliability. Manually powering on the speaker is the simplest workaround.
• Limited wireless range – While rated for a 30-foot wireless connection, walls, interference, and high frequencies can reduce this significantly. Position the S1 Pro as close as possible to your wireless source for best results. Switch to a wired connection for events with extremely long distances between performer and PA.

Physical Damage and Durability Concerns

The S1 Pro is reasonably durable for regular portable use, but it’s far from indestructible. Owners have reported issues resulting from physical damage:

• Scuffs and scratches – The speaker cabinets have a finish that can show signs of wear over time, especially when transporting the speakers frequently. Use carrying bags or cases and handle the S1 Pro carefully to minimize scuffing.
• Dents and cracks – Dropping or imparting a heavy impact on the S1 Pro can result in dents, cracks, and structural damage. Always use both hands when carrying and keep the speakers stable on flat, rigid surfaces when in use. Inspect routinely for any new physical damage.
• Moisture damage – Exposure to liquids can cause corrosion of electrical components in the S1 Pro. Never leave the speakers exposed to rain or water splashing. Wipe off any minor moisture immediately. If moisture infiltrates internally, professional repairs will likely be needed.
• Component failures – Long-term wear eventually takes a toll on parts like amplifier circuits and speaker drivers. Higher use cycles will accelerate this aging process somewhat. But even with moderate use, components can fail after several years. Replacing individual parts may be possible, but often requires factory repair service.
• Faulty handles – The integrated handles receive a lot of pulling and tugging forces during transport. Some handles have loosened or detached partially as a result. Try to grasp the handles close to the speaker body to reduce straining the attachments. Handles can be re-glued or replaced if need be.
• Bad power ports – Repeated plugging and unplugging of the power cable can damage the input port. The port may need to be repaired or replaced completely if it is loose or not making good electrical contact. Avoid tugging cords at odd angles when disconnecting.
• Torn grille fabric – It’s fairly easy to snag and rip the cloth grille material on the S1 Pro, especially around the tweeter domes. Exposed speaker drivers affect sound quality and leave the components unprotected. Replacement grilles can be ordered if needed.

Setup, Configuration, and Control Difficulties

Given its extensive feature set, it’s not surprising that some users struggle with the initial setup process and finding the best configuration for their needs:

• Complicated app and menus – Bose didn’t exactly make the S1 Pro app intuitive or easy to navigate. Be prepared for a learning curve as you figure out how to access various settings and options. Having the user manual handy helps decipher the app’s cryptic icons and terminology.
• Confusion connecting multiple speakers – You can daisy chain multiple S1 Pros together for more coverage, but the process for setting this up can be nebulous. Carefully follow the daisy chaining instructions in the user manual, and make sure to designate one speaker as the master.
• ToneMatch limitations – The ToneMatch feature aims to optimize EQ settings for specific source instruments. But in practice, its presets are hit or miss depending on the individual instrument and player preferences. Some trial and error is required to find a ToneMatch setting that sounds good.
• Frustration with presets – In general, the S1 Pro’s effects presets garner mixed reviews in terms of sound quality. Take time to audition different options and tweak parameters to suit your needs. Create your own custom presets if the stock options don’t work for your situation.
• Can’t recall favorite settings – Once you dial in settings you like, make sure to save them as a custom preset so you don’t have to start from scratch every time. Give the preset a logical name that will help you remember the context for each one.
• Speaker placement challenges – Proper placement is crucial for any PA system, but takes some experimentation with the S1 Pro. Adjust the angle, height, distance, and orientation to reduce feedback, improve coverage, and get the best sound for your specific room.
• Learning auto features – Conveniences like the Auto-On and Speech mode require some practice to activate reliably and use effectively. Read up on triggering and configuring these auto functions in the user guide to reduce hassle and take full advantage of them.

Other Bose S1 Pro Complaints and Weaknesses

A few other gripes about the S1 Pro are worth quickly mentioning:

• Some users find the angled cabinet design makes the S1 Pro prone to tipping over if bumped or placed on uneven surfaces. Using stands can improve stability vs sitting directly on the floor.
• The battery takes a painfully long time to fully recharge from empty – up to 4 hours. Plan ahead and charge up well before events. Have a backup plan to switch to wired power as needed.
• Wind noise and lackluster rejection of plosives and vocal popping are complaints when using the S1 Pro for speech and presentations. Use a foam windscreen and/or an off-axis mic positioning to help mitigate these issues.
• There are some reliability complaints around the microphone input jack and associated electronics, with reports of dropouts or channels intermittently cutting out.
• Bass and mixing presets lack customization options according to some users who want more flexibility fine tuning the effects. An equalizer would help enormously.
• A standard threaded mounting socket for adding the speaker to a tripod or stand would add great versatility but is absent from the current S1 Pro design.
